Hi all,

I'm trying to implement an AM demodulator. I was planning to send the real samples through an IQ demodulator and then take the magnitude of I+Q to get the demodulated audio. I can't figure out how to implement the magitude(I+Q) operation though. Is there a provided magnitude processing block or even a square root one? This must be really easy but I can't find what I want in the docs.

Thanks for your time,
David Carr
